DALI rotary potentiometer Tunable white, soft locking, light control. DALI rotary potentiometer Tunable white with soft locking, supplies the necessary control current for additional DALI participants in active operation on mains voltage, parallel connection of max. 4 active DALI potentiometers possible, without mains voltage in passive operation, in conjunction with DALI voltage as an additional control point, switch-on brightness can be stored in a power failure-safe manner, basic brightness can be adjusted, for switching and controlling electronic ballasts and Tronic transformers with DALI/DSI interface (e.g. for fluorescent lamps and low-voltage halogen lamps), control takes place via central telegram (broadcast), short-circuit-proof and overload-proof (electronic fuse), with push-off switch, with screw terminals. Note: Not suitable for combination with other DALI sensors or control centers.
